Application filed January 21, 1921. Serial No. 438,952.

To all whom t may concern: y

Be it known that I, FREDERICK A. Pmis- ToN, a citizen of the UnitedStates or America, residing at yHighland Park, in the county of Lake andState of Illinois7` have inventedcertain new and useful Improvements inAnticreeper Tie-Plates, of which the 'following is a specification. l v

My invention relates to an anticreeper tie plate.

It is common practice in the construction and maintenance of railways toprovide metal4 plates on the ties underneath the rails, particularlywhen soft wood ties are used, in order to provide a seat 'for therailswhich plates protect the ties from unnec-` essary wear and serve toprevent turning n movement of the rails about their Alongitudinal axeswith the consequent liability to cause train derailments and the cuttingof the ties by the rail base flanges. It isv also` 4common practice toprovide anticreeping devices to prevent longitudinal creeping oi therails on the ties. The anticreeping devices are embodied in structuresseparate and distinct from the ordinary tie plates and add considerableto the cost of track lequipment and maintenance. The primary object ofmy invention is to provide an improved `combination anticreeper and tieplate which isof simple construction and eiiicient in operation or use.

Some attempts have 'been made to pro vide a device of this general typein whichv a jaw is provided adjacent one end of a tie plate ofordinary-width and a spike open-` ing at the other end, the jaw beingarranged j so asl to grip one of the base ianges of the rail when aspike is driven through said opening into the tie. The passing of atrain over the track results in the rails being subjected.` to awave-like motion, the eect of which is to tilt each tie plate upwardlyin the direction of movement of the train as the wheels approach thetie, and to tilt the tie plates in the opposite direction as the wheelspass over and beyond-the tie. This rip-anddown tilting .or rockingmovement ofthe tie plate causes unnecessary wear on the bottom of therail base and also causes the edges ot the tie plate to cut into theJface of the tie considerably bruising and damaging it; This tiltingaction of the tie,

and in enlarging the spike openings. If a tie plate of ordinary width isanchored to the tie in a manner to obviate saidtltin'g or `rockingmovement the disadvantages above noted are to a considerable extent`overcome, but in that ycase the wave-like motion of the rail tends tospring thejaw or' the plate to such `an extent that it no longersecurely gripsthe rail base flange. Consequently such a tie `plate isineffective as an anticreeping device. A more specific object of myinventionis towprovide a tie plate consisting of two relativelyV narrowindependent members which are` adapted to be placed side by side on `thetie to provide a seat for the rail, each member adjacentv one end havinga gripping jawy formed integrally ytherewith .and adapted to fit overtively, engage the opposite rail base flanges,

each member adjacent the other end having a spike opening which extendspartially beneath the railbase so that. when a spike is fdriventherethrough `the member is moved transversely with respect tothe rail ybase andthe jaw is forced 'into' eiiective holding engagement with vtheadjacent flange.A l l The invention consistsin the novel and improvedconstructions, arrangements and.

devicesI Pto be hereinafter described and claimed for carrying out theabove stated objects and lsuch other incidental object-s as will appearfrom the following description of a preferred embodiment of theinvention illustrated injthe accompanying drawings, in which- Fig; l isa-plan view of a device embodvingthe principles of my invention,

Fig. 2 is a sectional view taken onk the line' 2 2 of Fig. l showing theapproximate position oii' the device relative to the rail basejust priorto. driving a spike through the spike opening provided in the deviceopposite thejgripping jaw, and y Fig. 3 is a view similar toy Fig. 2showing the yposition of the `device relative to the rail base after thespike has been driven home.

Like characters of reference designate like parts in the several views.

Referring to the drawings it will be seen `that the combinationanticreeper and tie plate shown therein comprises a parof Ilativelynarrow members 5, 5 placed side by side a short distance apart on thetie underneath the rail G longitudinally with respect to the tie 7 buttransversely with respect to the rail. The 'members 5, 5 are each formedfrom a plate by rolling,- and provided adjacentone end with anoverhanging jaw 8 which is adapted to fit over one of the rail baseflanges, The members 5, 5 are arranged so that the respective j awsS, 8thereof en- `sage the opposite' rail base flanges. rllhe jaws 8, S areeach formed or shaped so that the aneularit of the bearino` vsurface 8thereof, before the member is in operative posi-tion under the railbase, is less than that of' the tcp surface of the rail base flange'with which it comes into contact when the member is in operativeposition under1 the rail base, consequently said jaws have to be forced'open or sprung,` slightly upwardly when the members are in operativeposition under the rail base.

rl-he members 5, 5 are each provided in the end opposite the jaw Szwitha spike opening 9 which is located with respect to the jaw 8 vand thewidth of the rail base,

secure that end of the plate to the tie. The,

openinnll is located far enough away from the aw so that when the spike12 is driven home there will be notendency to spring the jaw open andthereby loosen or weaken its hold upon the rail base flange.

A plurality of stiflj'ening ribs 13 of any de-V sired shape arepreferably provided o n the bottom side .of the plats to prevent dis-`place. nt of them on the tie.

The shape of t-hejaw 8 and the location of the spike opening 9, withrespectto the j awy he width'of the rail, result in the pla e Vb firmlyanchored to the rail base the `spike 110 is driven into. the tie. Thevspikes-10 and 12 firmly anchorv the ate tothe tie= 'lV ith acombination antieeper and tie plat-e` constructed according to. myinvention the rails are held at each tie'against creepage in eitherdirection.. rlhe two tie plates being relatively narrow in widthand'independent of each other, are

j not subjected to up-and-down or rocking movements, atleast to.anyappreciabl'e eX` tent, when the rolling stock passes: over the rails.Tl'i'erespective jawsV of* the tie plates are not pried up when therolling ,ose

stock passes over the'i'ails, as is the case when relatively wide tieplates are used, and they do not, there-tore, loose their grip on therail base flanges.
